To start this is an 1880 house, that is not perfectly level, square, plum etc. Although I have spent a painstaking amount of time doing my best to get a lot of it that way. after a year of spending every spare minute and weekend gutting, framing, wiring, plumbing, etc I handed the keys over to a local sheet rocker that came recommended. the attached pictures are his progress up to this point. I'm not a sheet rocker. I've hung it, I've never mud it. it's not that I couldn't, it's that I am very particular and want it perfect, so I hire a professional. the old saying, "you can't beat a man at his trade" I'm an electrician by trade so I am a firm believer in this. - so getting to the pictures and sheet rock. how the sheet rock has been and is being hung doesn't set well with me. I would never hang it like that. and I've brought this up to my contractor very respectfully multiple times that I'm concerned with the gaps, excess screws everywhere that missed studs, shower enclosures not having sheet rock over the fiberglass screwing flange, etc. i could go on, but the pictures tell the story. my contractor has repeatedly told me to not worry, he prefills his sheet rock with durabond. it's harder than the sheet rock, he gives a 2 year crack warranty, I haven't paid him a cent, when he primes the house any imperfections in the sheet rock will be visible for him to fix etc, etc. SO CAN DURABOND REALLY PREFILL THOSE MASSIVE GAPS??? he started prefilled about a half inch gap in the downstairs living room ceiling and it was literally drooping out of it! ( picture attached) I'm so far into it at this point I have choice but to let him finish. nobody else in their right mind would pick up this job to mud it with the sheet rock hung like that. my previous sheet rocker (40 years in the trade, and does impeccable work) wouldn't touch this with a 40 for pole!!!
